District Attorney Don Anderson said he believes Piveronas was shot twice and that his condition is serious.

Officials did not say what may triggered the shooting, or what type of weapon was used. Anderson said his investigators are still working on the case.

The shooting stunned the couple's next door neighbor, Sally Manthey.

"It's just a shock really," she said. "They seemed to be getting along."

In an April 2012 Facebook posting, Bob Piveronas wrote: "Happily Married To The Woman of My Dreams, Paula Ann!!"

Manthey said she doesn't recall ever hearing the couple fight.

She said she'd visited with them during a memorial service for a neighbor a week ago and that Bob Piveronas was attentive, as seemed usual, to his wife. She saw them again on Sunday when some visiting family was leaving.

"They seemed to be enjoying their company and having a good time with them," Manthey said.

She said she liked both Bob and Paula Piveronas but that Bob was the more friendly of the two.
